A small agency
that ships.

lost end found is an independent product agency in the United Kingdom. We design, build and ship software end to end — and we keep the team deliberately small so the people who scope your project are the ones who write the code.

// The agency

We build for the internet, one app at a time — and we've been doing it for over a decade.

Most of what we make begins as our own itch. A reporting tool that should exist but doesn't. A plugin for the editor we live in. A small Mac utility that fixes one annoying thing perfectly. We ship it, we use it every day, and the good ones become products other people rely on too.

The same instincts go into client work. We take on a small number of projects each quarter — web platforms, native apps, storefronts — and treat them the way we treat our own: scoped honestly, built to last, shipped without drama.

How we work

PRINCIPLES
01

Small, sharp, shipped

No layers, no hand-offs. The person who understands the problem is the person who builds it — and we'd rather ship something small and real than plan something big forever.

02

End to end, honestly

From design and build to App Store and the integrations between your tools — we scope what's needed, say how we'd ship it, and flag what isn't worth doing.

03

Built to outlive us

Clean stacks, sensible defaults, privacy by default. Our own apps store settings locally and in your iCloud — no tracking, no analytics. Client code is yours, documented and handed over.

Larry started lost end found to build the kind of software he wanted to use — tiny, sharp tools that do one thing exceptionally well. Today that's twenty-plus shipped products across macOS, iOS, the web and the editors people live in, plus client work for teams who need something built properly.
